Question

Al + Cl2 = Al + HCl =Al2O3 + KOH =Al2O3 + CaO =Al2O3 + H2SO4 =Al(OH)3 + KOH =Al(OH)3 =Al(OH)3 + HNO3 =​

Answer 1

Ответ:

Объяснение:

2Al +3 Cl2 = 2AlCl3

2Al +6 HCl = 2AlCl3 +3 H2

Al2O3 + 2KOH =2KAlO2 + H2O

Al2O3 + CaO  реакция не идёт

Al2O3 + 3H2SO4 = Al2(SO4)3 + 3H2O

Al(OH)3 + KOH = KAlO2 + 2H2O

2Al(OH)3 = Al2O3 +3 H2O

Al(OH)3 + 3HNO3 = Al(NO3)3 +3 H2O

Answer 2

Let's go through each chemical reaction step by step:

1. Al + Cl2 = AlCl3 Aluminum (Al) reacts with chlorine gas (Cl2) to form aluminum chloride (AlCl3).

2. Al + HCl = AlCl3 + H2 Aluminum (Al) reacts with hydrochloric acid (HCl) to form aluminum chloride (AlCl3) and hydrogen gas (H2).

3. Al2O3 + KOH = KAlO2 + H2O Aluminum oxide (Al2O3) reacts with potassium hydroxide (KOH) to form potassium aluminate (KAlO2) and water (H2O).

4. Al2O3 + CaO = CaAl2O4 Aluminum oxide (Al2O3) reacts with calcium oxide (CaO) to form calcium aluminate (CaAl2O4).

5. Al2O3 + H2SO4 = Al2(SO4)3 + H2O Aluminum oxide (Al2O3) reacts with sulfuric acid (H2SO4) to form aluminum sulfate (Al2(SO4)3) and water (H2O).

6. Al(OH)3 + KOH = KAl(OH)4 Aluminum hydroxide (Al(OH)3) reacts with potassium hydroxide (KOH) to form potassium aluminate (KAl(OH)4).

7. Al(OH)3 = Al2O3 + H2O Aluminum hydroxide (Al(OH)3) decomposes to form aluminum oxide (Al2O3) and water (H2O).

8. Al(OH)3 + HNO3 = Al(NO3)3 + 3H2O Aluminum hydroxide (Al(OH)3) reacts with nitric acid (HNO3) to form aluminum nitrate (Al(NO3)3) and water (H2O).
